Inner eyeball has a visible-light receptor-cell layer {vision, anatomy}.
occipital lobe
Areas V2 and V4 detect contour orientation, regardless of luminance. Area V4 detects curved boundaries.
temporal lobe
Middle temporal-lobe area V5 detects pattern directions and motion gradients. Dorsal medial superior temporal lobe detects heading.
temporal lobe: inferotemporal lobe
Inferotemporal lobe (IT) detects shape parts. IT and CIP detect curvature and orientation.
retina and brain
Brain sends little feedback to retina [Brooke et al., 1965] [Spinelli et al., 1965].
pathways
Brain processes object recognition and color from area V1, to area V2, to area V4, to inferotemporal cortex. Cortical area V1, V2, and V3 damage impairs shape perception and pattern recognition, leaving only flux perception. Brain processes locations and actions in a separate faster pathway.
